A Study of Ixazomib Administered in Combination With Lenalidomide and Low-Dose Dexamethasone in Patients With Newly Diagnosed Multiple Myeloma
Study Details
Study Description
Brief Summary
The purpose of Phase 1 of this study was to determine the safety, tolerability, maximum tolerated dose (MTD), and recommended Phase 2 dose (RP2D) of oral ixazomib administered in combination with lenalidomide and low-dose dexamethasone in participants with newly diagnosed multiple myeloma (NDMM). The purpose of Phase 2 of this study was to determine the overall response rate (ORR) and further evaluate the tolerability and toxicity of the combination of oral ixazomib, lenalidomide, and low-dose dexamethasone in patients with NDMM.

Phase 1/Phase 2 |
Detailed Description
The drug being tested in this study is called ixazomib. Ixazomib was being tested to treat people who had newly diagnosed multiple myeloma who had not previously received systemic treatment. This study was conducted in two Phases. Phase 1 looked at side effects and lab results in people who took ixazomib to determine the MTD and RP2D. Phase 2 looked at overall response rates and side effects in people who took ixazomib.
The study enrolled 15 patients in Phase 1 and 50 patients in Phase 2. Participants in Phase 1 were assigned to cohorts and received ixazomib 1.68, 2.23, 2.97, or 3.95 mg/m^2 in addition to dexamethasone 40 mg and lenalidomide 25 mg. Participants in Phase 2 received ixazomib 4.0 mg fixed dose in addition to dexamethasone 40 mg and lenalidomide 25 mg. In both Phases study treatment was administered in 28-day Cycles as follows: ixazomib Days 1, 8 and 15, dexamethasone Days 1, 8, 15 and 22, and lenalidomide 25 mg Days 1 through 21.
This multi-center trial was conducted in the United States. The overall time to participate in this study was 12, 28-day cycles with the option to continue into a maintenance portion in the absence of disease progression or unacceptable toxicity. Participants made multiple visits to the clinic and a final visit 30 days after last dose of study drug for a follow-up assessment.

Outcome Measures
Primary Outcome Measures
- Phase 1: Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) as a Measure of Safety and Tolerability [Until occurrence of progressive disease or unacceptable toxicity (Up to 336 days)]
An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly; or a medically important event.
- Phase 2: Objective Response Rate (ORR) Following Treatment With the Combination Of Oral Ixazomib, Lenalidomide And Low-Dose Dexamethasone [Until occurrence of progressive disease or unacceptable toxicity (Up to 787 days)]
ORR was defined as the percentage of participants with Complete (CR) + Very Good Partial Response (VGPR) assessed by the investigatory using International Myeloma Working Group (IMWG) Criteria. CR=Negative immunofixation on the serum and urine and; disappearance of any soft tissue plasmacytomas and; < 5% plasma cells in bone marrow. VGPR=Serum and urine M-protein detectable by immunofixation but not on electrophoresis or; 90% or greater reduction in serum M-protein plus urine M-protein level < 100 mg per 24 hours.
- Phase 1: Recommended Phase 2 Dose of Ixazomib Given in Combination With Lenalidomide and Low-Dose Dexamethasone [Until occurrence of progressive disease or unacceptable toxicity (Up to 336 days)]
RP2D will be determined based on number and type of adverse event and serious adverse events, assessments of clinical laboratory values, neurotoxicity grading, and treatment discontinuation.
- Phase 1: Maximum Tolerated Dose (MTD) of Ixazomib Administered Weekly in Combination With Lenalidomide and Low-Dose Dexamethasone [Until occurrence of progressive disease or unacceptable toxicity (Up to 336 days)]
MTD of ixazomib will be determined by assessing adverse events and serious adverse events, clinical laboratory values, neurotoxicity grading, and vital sign measurements.
- Phase 2: Percentage of Participants With Grade 3 or Higher AEs, SAEs and Treatment Discontinuation [Until occurrence of progressive disease or unacceptable toxicity (Up to 787 days)]
An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly; or a medically important event.

AUC(0-168) is a measure of the area under the plasma concentration-time curve from time 0 to 168 hours postdose for Ixazomib.
- Phase 1: Rac: Accumulation Ratio of Ixazomib [Cycle 1, Day 15]
The accumulation ratio (Rac) was estimated as the ratio of AUC(0-168) on Day 15 to the AUC(0-168) on Day 1. AUC(0-168) is the area under the plasma concentration-time curve from time 0 to 168 hours postdose for ixazomib.

Emax is the maximum observed inhibition of whole blood 20S proteasome. The pharmacodynamics 20S Proteasome samples were collected and the assays were performed; however, concerns about the third-party laboratory's performance of the blood 20S proteasome activity assay were identified that precluded the ability to confirm the accuracy of the data so no data is reported.
- Phase 1: TEmax: Time to the Maximum Observed Inhibition of Whole Blood 20S Proteasome [Day 1 predose and at multiple time points (up to 168 hours) postdose and Day 15 predose and at multiple time points (up to 336 hours) postdose]
TEmax is the time to the maximum observed inhibition of whole blood 20S proteasome. The pharmacodynamics 20S Proteasome samples were collected and the assays were performed; however, concerns about the third-party laboratory's performance of the blood 20S proteasome activity assay were identified that precluded the ability to confirm the accuracy of the data so no data is reported.

Title | Phase 1: Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) as a Measure of Safety and Tolerability |
---|---|
Description | An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly; or a medically important event. |
Time Frame | Until occurrence of progressive disease or unacceptable toxicity (Up to 336 days) |
